Determine whether 5^25m^2 • 5^25m is equivalent to each of the following expressions.
I’ll give brainliest
Answer:
None of the listed expressions
Step-by-step explanation:
Using the Product Law of Exponents, we can simplify 5^25m^2 • 5^25m into 5^(25m^2 + 25m).
Simplify:
5^25m(m + 1)
In this case, none of the following responses are equivalent. The first two are incorrect because you can't add variables that are set to different powers and the last one is incorrect because if you wanted to change the base from 5 to 25, you would divide the exponent by 2 instead of take the square root.

A company sells three types of gift baskets. The basic basket has two movie passes and one package of microwave popcorn, and costs $15.50. The medium basket has two movie passes, two packages of microwave popcorn, and one DVD, and costs $37. The super basket has four movie passes, three packages of microwave popcorn, and two DVDs, and costs $72.50.
Create a system of equations and solve using matrices to find the price of each basket item.
The price of each movie is $7, the price of each microwave popcorn is $1.50 and the price of each DVD is $20.
Let x represent the cost of each movie, y represent the cost each microwave and z represent the cost of each DVD.
For the basic:
2x + y = 15.50 (1)
For medium:
2x + 2y + z = 37 (2)
For super:
4x + 3y + 2z = 72.50 (3)
[tex]\left[\begin{array}{ccc}2&1&0\\2&2&1\\4&3&2\end{array}\right] \left[\begin{array}{c}x&y&z\end{array}\right] = \left[\begin{array}{c}15.5&37&72.5\end{array}\right] \\\\\\ \left[\begin{array}{c}x&y&z\end{array}\right] =\left[\begin{array}{ccc}2&1&0\\2&2&1\\4&3&2\end{array}\right]^{-1}\left[\begin{array}{c}15.5&37&72.5\end{array}\right]\\\\\\ \left[\begin{array}{c}x&y&z\end{array}\right] = \left[\begin{array}{c}7&1.5&20\end{array}\right] =[/tex]
The price of each movie is $7, the price of each microwave popcorn is $1.50 and the price of each DVD is $20.

which is a better buy six cans for $7 or 8 cans for $9?
Answer:
8 cans for 9$
Step-by-step explanation:
buy 8 cans for 9$
The 8 cans for $9 is better than six cans for $7.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We need to find better buy six cans for $7 or 8 cans for $9.
Let's find the unit rate of both the quantitites;
six cans for $7
Then one can = 7/6 = 1.16
Therefore, 8 cans for $9.
one can = 9/8 = 1.125
Hence, the 8 cans for $9 is better than six cans for $7.

In a parallelogram ABCd, angle a + angle b = ?
Answer:
180
Step-by-step explanation:
Easy way: they're conjugate angles relative to the two parallel sides and the trasversal joining them, their sum is 180.
Longer(??) way: In a parallelogram two opposite angles are congruent. Since the sum of the internal angles is 360, a pair of two different angles must sum to 180.
Step-by-step explanation:
In a Parallelogram ABCD , ∠ A + ∠B = 180°
Since , The Adjacent angles in a Parallelogram are Supplementary.
Additional comment:
• In a Parallelogram, Opposite angles are equal
•The sum of two adjacent angles is 180° called Linear pair.
